Request of new Function for the Subject - add Date

Dear all,

Is there a possibility to include in the code of the plugin the function that in the subject the creation date of the ticket is displayed? We would like the subject to look like this:

- Ticket created on 2020-05-09 // Ticket ID: 0004563

**Mail subject should then look like this:** [Ticket#202005090004563] <summary>

Thanks in advance!

Regards,
Giuseppe
